Control Effects of Tank Mixtures of Chlorantraniliprole, Avermectin and Bacillus thuringiensis against Plutella xylostella in Different Areas
摘要
Abstract
We find out the resistance status of chlorantraniliprole,avermectin,and Bacillus thuringiensis,and field control effect of tank mixtures of 3 insecticides against different Plutella xylostella field populations in Tonghai Yunnan Province,Wuhan Hubei Province,and Haikou Hainan Province,to provide a reference for the strategy of resistance management to P xylostella,and promote chemical pesticide reduction and control.The resistance and field efficacy of the 3 insecticides were tested by leaf dipping bioassay and field trial.The results indicated that 3 field population ofP.xylostella have produced a high level of resistance to avermectin,with the resistance ratios of 276～ 1062 fold.The resistance ratios to chlorantraniliprol were 60～671 fold,which tested moderate to high level of resistance.Moderate and low level of resistance to B.thuringiensis was found with the resistance ratios of 5.1～15.2 fold.The field control effect and resistance level displayed a consistent trend.The effect of B.thuringiensis reached more than 70％ after 7 days,while the chlorantraniliprole and avermectin were less than 60％.The field control effects of tank mixtures of chlorantraniliprole,avermectin and B.thuringiensis were 88.70％ and 81.50％ in the above areas respectively.The difference between the two tank mixtures and their single agents was significant.Therefore,it was recommended to mix or to rotate using B.thuringiensis in order to improve the control effect of P.xylostella.关键词
